LOGGING VEHICLE Filed Aug. 6. 1929 5 Sheets-Sheet 5 EMM Patented May 2e,1931 UNITED STATES PATENT OFFICE HARRY IH. RICHMOND, OF PORTLAND,OREGON, ASSIGNOR T ELECTRIC STEEL FOUNDRY COMPANY, 0F PORTLAND, OREGONLOGGING VEHICLE Application filed August 6, 1929. Serial No. 383,970.

This invention relates generally to the logging industry, andparticularly to logging vehicles. v

The main object of thisinvention is to construct a logging vehicle ofthe high arch type in aV manner which will permit the use of lightersections than are otherwise necessary.

The second object is to employ steel castings forthe purpose ofeliminating expensive and uncertain welding operations.

The third object is toprovide a special form of joint or connectionbetween the various frame elements.

The fourth object is to facilitate the assembly of the elements, as wellas taking same apart for shipping or storage purposes.

The fifth object is to provide a connection between the high archvehicle and its hauling tongue which will permit a change in therelation of the arch and its primemover by the mere substitution of adifferent shaped hauling tongue.

The sixth object is to so construct the vehicle as to make it possibleto better control the dimensions thereof by putting it in a form whichbetter ada-pts itself to casting methods.

The seventh object is to facilitate the assembling of the vehicle in thefield.

The eighth object is to provide an additional reinforcement for theconnecting means in the form of a throu h bolt.

These, and other objects, wi l become more apparent from thespecicationfollowing as illustrated in the accompanying drawings inwhich:

Figure 1 is a plan of the vehicle showing the method of attaching sameto a tractor.

Figure 2 is a side elevation of the vehicle as shown in Fig. 1.

Figure 3 is a vertical section along the line 3--3 in Fig. 2.

Figure 4 is a section taken along the line 4 4 in Fig. 2.

Figure 5 is a plan of one side of the tongue.

Figure 6 is a side elevation of the tongue side shown in Fig. 5. I

Figure 7 is a section along the line 7-7 in Figure 2.

Figure 8 is a section along the line 8 8 in Fig. 5.

Figure 9 is a section along the line 9-9 in Fig. 5.

Figure 10 is a plan of the neck with parts broken away in section.

Figure 11 is a side elevation of the neck i with a part broken away insection.

Figure 12 is a section along the line 12-12 in Fig. 2.

Similar numbers of reference refer to similar parts throughout theseveral views. Referring in detail to the drawings, there is shown avehicle consisting of a pair of spaced crawler type of trailing elements15 which are pivotally attached by means of the pins 16 between theforked ends 17. The tongue portion 18 is attached to the forked ends 17by means of the pins 18-A. The forward ends 19 of the tongue sections 18are flanged and provided with a pair of projecting lugs 20 which t intothe recesses 21 of the body 22 of the neck 23, whose middle portion isbent (as shown) for reasons which will be better understood from whatfollows.

The head 24 is provided with an opening 25 which receives the shank 26of the ball 27 which fits into the socket 28 mounted on the frame 29 ofa cable winding hoist which is provided with a drum 30 upon which iswound a cable 31. The shank 26 is held in position by a nut 32. The ball27 is held in the socket 28 byl means of a cover plate 33 which is`heldin position by means of the bolts 34. rllhe flanges 19 are held againstthe anges of the body 22 by means of the bolts 36, whichv could ofcourse extend entirely across the body 22 if desired. 'The lugs 20 aresomewhat tapered and fit closely against the sides of the recesses 21making a rigid connection when the bolts 36 are pulled up tight. It isalso desirous to provide a continuous hole 37 through the flanges 19 andthe body 22 for the bolt 38, which may be employed as an additional`means for uniting the parts of the vehicle.

It will be noted in Figures 8 and 9 that the tongue 18 is somewhatsquare in cross section and hollow, giving the maximum strength for agiven'weight.

5 section and its forked ends 17 are attached to the pins 16 of thetrailing elements 15, as previously described. On top of the arch 40 ismounted a horizontal roll 41 behind which is a pair of spaced verticalrolls 4Q between which, and over the roll 4l, the cable 3l passes to thechoker hooks 43 by means ofwhich they are secured around the logs 44.

Between the forward ends of the tongue 18 and the upper portions ofthearch 40 are the tie members 45 preferably provided with a pluralityof holes 46, by means of'which the length of the tie 45 may be variedfor the purpose of changing the angular relation lbetween the arch 40and the tongue 18. This connection is shown in Figure 4.

It can thus be seen that the upright position of the arch 40 can bevaried at will as may be found necessary, due to the varying conditionsunder which the logging is being done, such'as contour of the ground,size of logs and height of hitch or connection to the tractor itself. Itcan also be seen that by varying the shape of the neck 28 the vehiclemay be made to adapt itself to a wide range of tractor mountings. Inother words, where the hitch is lowered, as it might be on sometractors, a neck of greater curvature should be provided for the:purpose of allowing a small amount of clearance for the ends of thelogs 44.

I claim:

1. A logging vehicle consisting of a pair of forked tongue memberssloping upwardly towards the forward end, a neck joining the forwardends of said tongue, an arch spanning said forked ends and hingedlyconnected thereto, brace means between said arch and tongue and groundengagingelements supporting the opposite sides of said arch.

2. In a logging vehicle the combination of a pair of ground engagingelements, a forked tongue extendin 4from each of said elements slopingforward y and upwardly toward each other, a downwardly curved neckconstituting a hitch formin a means for uniting said curved tongue en sinto a rigid structure, an arched frame having its ends hingedly mountedabove said ground yen aging -elements, said arched frame having airloading rolls at the top thereof, and brace means for maintaining therelation between said arch and tongue means.

3. In a loggin vehicle the combination of a pair of groun engagingelements of the crawler type, a high arch frame spanning said crawlerelements and hingedly connected to each of same, a tongue hinged to thefoot of eachside of said high arch frame extending upwardly, forwardlyand inwardly toward each other, an adjustable brace having their forwardends curved toward each other, the adjacent faces thereof havlngprojecting lugs formed thereon, a curved neck between said adjacenttongue ends having recesses therein adapted to receive said lugs, and aball and socket connection at the forward endf of said neck forattaching same to a tractor. n

5. In a high arch vehicle the combination of a pair of ground engagingelements having an upright U-shaped arch and a forwardly and upwardlysloping U-shaped tongue attached thereto at the open ends thereof bymeans of a hinge connection, and brace means for holding said uprightarch and sloping tongue in a desired relation.

6. In a high arch vehicle the combination of a pair of laterally spacedground engaging elements of the crawler type, an u right arched framehaving each open end t ereof forked to straddle said ground engagingelements and having a pivotal connection thereto, a U-shaped tonguesloping upwardly and forwardly having its open ends forked and hingedlyattached to the lower ends of said arch frame, adjustable brace meansbetween said tongue and frame, and a downwardly curved neck having meansfor bolting same at the forward end of said tongue, said neck having auniversal connection thereon.
